  FWIW this is likely to be a libpth issue, which in turn may be a
makecontext/setcontext issue in the glibc. You have to contact porters
about that.

I know for sure, that the makecontext/setcontext have not yet been
implemented on hppa.
Are they required for dirmngr ?

  Okay and that's what the strack dump shows. libpth uses
make/setcontext when available, and else uses sigaltstack tricks to do
threads. I assume something is broken in the latter code, maybe with
recent compilers.

Helge, could you test whether rebuilding pth with -O0 fixes the dirmngr
problem for you?

I'm cloning this to glibc and pth, so that the respective maintainers are
aware of this issue.

FYI: glibc 2.7-14 has just been uploaded to unstable with a patch implementing
*context() on sparc and hppa.

Subject: fixed pth on its way

Date: Mon, 06 Oct 2008 22:11:35 +0200

Hi,

I have NMUed to build-depend on the new glibc on hppa and verified that
the dirmngr segfault goes away with that version.
Given that the problem is probably not dirmngr-specific and will go away
once a newer libpth is installed, I suggest to close this bug without an
upload once pth 2.0.7-10.1 hits lenny.

Kind regards
